Rendering problem when using Sony Vegas Pro 12 64bit in Windows 8.
I just can render MOV format without any problem,
MP4 and other format will render a Black screen video (H.264/MPEG-4 AVC) for the imported video (codec: Sony AVC). (the Sony Vegas element is still showing, which means not black screen).
There is no problem when previewing the whole video.
How to solve this problem?
Help is needed please

Save your project, then did you try rebooting ?
Did you try disabling GPU acceleration ?
All other formats affected? Is AVI export is affected ? Is image sequence export affected ?
Tried disabling GPU acceleration, not working
by the way , my GPU is Nvidiao GEFORCE GT750m.
AVI is also affected.
Audio is working in every format I tested, but video is still blank.
Windows movie maker for windows 8 can render this video (originally is a mp4 format too, it is a video I recorded by using my Sony Xperia S) into MP4 format.
I am going to record a new video (by using a software called shadowplay, alike fraps) and re-render it in Sony Vegas, will post the result later.
extra: I have the experience of using Sony Vegas Pro 9 32bit in my desktop before, rending works flawlessly.
Are both Sony AVC MP4 and Mainconcept AVC MP4 affected ?
I was going to suggested updating nvidia drivers, but I doubt it will help (since you tried disabling GPU accel, and preivew is OK in vegas)
As a temporary workaround , you can use debugmode frameserver to frameserve into another encoder
You can also try asking at the Sony Vegas forum, but the black screen seems to occur frequently with newer versions of Vegas
